Canon expands broadcast and Cinema EOS system with new servo zooms
Canon has expanded its Cinema EOS System with the launch of the CN7x17 KAS S – its first-ever cinema lens to feature a servo drive unit, designed for broadcast and handheld use with large sensor cameras. Canon is also reaffirming its position as a leader in the 2/3” TV lens market with the launch of the HJ18ex7.6B IRSE S/IASE S, the successor model to the popular HJ17ex7.6B IRSE A/IASE A, offering enhanced performance, specifications and usability.
CN7x17 KAS S – Super 35mm sensor optics
The CN7x17 KAS S has been created for the world of TV production – a fast-paced, mobile environment for which conventional Super 35mm format cine lenses were not designed. To support operators in this field, Canon’s new cine-servo lens combines decades of experience in the design of market-leading broadcast lenses with technology derived from its high-performance cine zooms – creating a tool of unprecedented quality, versatility and usability.
With a best-in-class focal length of 17-120mm, the lens is tailor-made for camera operators in traditional broadcast environments, whilst retaining the benefits of Canon’s renowned cine lenses for movie productions where a more fluid shooting style is required.
The new cine-servo lens has been designed to respond to the evolving needs of broadcast professionals, who are increasingly turning to large sensor cameras across a wide range of production categories, from drama to documentaries and current affairs. Offering operators the best of both worlds, it provides the functionality expected from traditional broadcast lenses whilst also capturing video of the highest quality with a distinct ‘cinematic look’. Both EF-mount (CN7x17 KAS S /E1) and industry-standard PL-mount (CN7x17 KAS S /P1) variants will be available.
Built to exacting optical standards, the cine-servo lens leverages Canon’s long-established expertise in lens design. Delivering the quality needed to shoot in 4K, the 7x optical zoom enables a hugely versatile 17-120mm focal length with a maximum T-number of T2.95, providing the flexibility to cover an unparalleled range of shooting situations with a lens of this type.
The servo drive unit makes the CN7x17 KAS S ideal for use in mobile productions such as documentaries. The drive unit is the same size as those on typical portable lenses, providing the same feel in operation, and making long shoots more comfortable. High speed zoom, iris and focusing operation allow operators to respond rapidly to changes in a scene, while low speed drive functionality offers unrivalled control over slow zooming to ensure the desired effect can be achieved. Immediate start-up means shots won’t be missed in dynamic situations.
The lens is also perfectly suited to tripod-mounted use during studio or outside broadcasts, for example. Zoom, focus and iris can all be controlled using Canon’s existing zoom and focus demands, providing precise and convenient control over vital image adjustments without the operator touching the lens. Virtual studio use is also supported thanks to a sophisticated 16-bit encoder output.
In line with Canon’s unsurpassed broadcast heritage, the new cine-servo lens is user-friendly, reliable and robust. The structural design has been developed to ensure high levels of ruggedness and reliability, even in unforgiving broadcast environments – combining the finest quality optics with a weather-and-shock-proof construction that makes it suitable for use in hostile conditions.
As part of the Cinema EOS System, the lens is equally at home on a movie set. The servo drive unit facilitates a mobile shooting style that is difficult to achieve with many existing cine lenses, and can also be removed completely to enable typical cinematic operation. Re-installation is quick and simple, with no adjustment of gear positions required. Canon’s renowned optical quality combines with support for standard accessories, including follow focus units and matte boxes, providing a truly versatile solution.
Compatible with a wide range of cameras, the CN7x17 KAS S also supports communication between lens and body. The EF-mount version utilises Canon’s own system, whilst the PL-mount variant is the first in the Cinema EOS series to support Cooke’s /i Technology. 12-pin serial communication is also supported.
The latest in Canon’s TV lens line-up
Canon has also announced the HJ18ex7.6B IRSE S/IASE S, a new and comprehensively enhanced ENG lens that acts as successor to the popular HJ17ex7.6B IRSE A/IASE A. This standard HD lens has been comprehensively upgraded in virtually every area, delivering enhanced performance, specifications and usability, with a reduction in weight also ensuring mobility1.
Canon’s trademark optics provide superior optical performance, delivering an increase in magnification to 18x and a longer focal length of 7.6-137mm. Minimum object distance is only 56cm, while a new drive unit provides enhanced usability, system support and operability.
First chance to see the lenses
Visitors to Canon’s booth (C4325) at the NAB Show 2014 will have the first opportunity to see these new lenses in action. NAB 2014 runs from 7-10 April at the Las Vegas Convention Centre in Las Vegas, Nevada, USA.
